Without hesitation -- the 6.5" coil. A GB2 rules the micro-world and the 6.5" will get you the micro nuggets. The 10" and 14" do not maximize the GB2's strong suit. If you want to go deep get a Minelab with a large coil.

Prospecting success, be it for HEARTS, TRUTH or GOLD, takes COURAGE and HONESTY to penetrate through the appearance of things, plus PATIENCE and FORTITUDE to work through the many layers of things of which both nature and human nature are composed.

6 & 10 rock my world. 6 amazingly sensitive and ez to work bouldery/trashy areas. 10" punches a mite deeper and great for the beach and alkaline soils and STILL very sensitive to small gold when balanced right.--John

Test swung the Gold Bug 2 and I am going to purchase. Question is, Which Coil/Coils (6", 10" or 14")?

Thanks,

My answer is all three....no doubt in my mind. I normally swing the 14". It finds a lot of meteorites for me. I also swing the 10" but not as much as the 14. It also has found a lot of meteorites.

I seldom swing the 6" but I know it would find the small surface stuff much better. Only issue with it is you have to swing like a helicopter blade to cover much area. So, each coil, for me, has a different purpose. But if I only had one choice, it would be the 14" coil. I have and use 3 GB2's.
